To all whom it may concern: Corresponding and like parts are referred Be it known that I, WILLIAM B. HAENSEL, to in the following description and indicated citizen of the United States, residing at in all the views of the drawing by the same New Orleans, in the parish of Orleans and j reference characters. 5 State of Louisiana, have invented certain j My improved nut lock consists essentially new and useful Improvements in Nut-Locks, i of a bolt 1 that is formed at one end with of which the following is a specification. suit-able head 2 and that is exteriorly The present invention coinprehends cerj threaded in proximity to its other end, as

A still further object of the invention is j plurality of bolts 1 being inserted through the registering openings in the fish plates 7 and the meeting ends of the rail sections 8.

After the nut has been retightened it is merely necessary to bend the loop slightly so that the beveled extremity thereof is again engaged with the outer face of the nut. The nuts may thus be independently tightened and the locking tongues reset without the necessity of removing the pin 10.

In practice the loops are never unbent unless it becomes necessary to remove the nuts from the bolts.

From the r'oregping description in connection with the accompanying drawing it will be apparent that I have provided an improved nut lock which may be advantageously employed in connection with jarring machinery or for other purposes where a positive lock is necessary or desired. Furthermore, the application of the nut lock may be expeditiously effected inasmuch as the tongue may be readily bent into an operative position with the use of a hammer or pair of pliers or like ordinary tools.

Having thus described the invention, what I claim is:

1. In a nut lock, the combination of a plurality of threaded bolts, nuts working on the respective bolts, each bolt having its extremity bent beyond the nut to form a loop for holding the nut against removal, and a member inserted in all of the loops to hold the bolts against relative turning movement.

2. In a nut lock, the combination of a plurality of threaded bolts, nuts working on the respective bolts, a reduced locking tongue extending from the threaded end of each bolt and bent to form a loop for holding the nut against removal, and a pin inserted in all the loops to hold the bolts against relative turning movement.

3. In a rail joint, the combination with the meeting ends of companion rail sections and a fish plate fitting against one side of the rail and spanning the joint, of threaded bolts passed through the fish plate and the respective meeting ends of the rail sections nuts working on the bolts, the extremity 0 each bolt being bent beyond the nut to form a loop for holding the nut against removal, and a member spanning the joint between the rail sections and inserted in all of the loops to hold the bolts against relative turning movement.

In testimony whereof, I athx my signature in presence of two witnesses.
